Muffet

She has become a mad queen her body has adapted to look more like a spiders but she now has two huge pincers and a poisonous stinger muffet has grown to be the same size as an adult allosaurus her spiders have adapted to look alot like the facehuggers from alien and they have the same use.

Her spiders rome all across the underground adapted to any environment looking for stronger monsters to infect and the weaker ones to feed to the queen once a monster is infected they’ll have no control of their body being forced to go to the burrow once there they’ll be forced to mutate into a half spider creature with no freewill.

When the “feast” first started muffet attacked and slaughtered her pet using its body as armour and decoration she treats her minions with the same respect if they do not deliver her food they’ll be killed and devoured.
